A simple example of the use of i in a complex number is 2 + 3 i. An imaginary number is a complex number that can be written in the form of a real number multiplied by an imaginary part, named i. The imaginary number (like 1 for Real Numbers) is i, which is the square root of 1. When imaginary numbers are squared, they give a negative result. The results of quadratic equation involve imaginary numbers. Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication. The imaginary number can be added with real number to form complex numbers.
